Application filed June .5,

To-aZZ whom it may con/0cm: I Be it known that I, PERCY E. YAUQHAN, a citizen of the United States, and resident of San Jose, in the county of' Santa Clara and 'State of--Ca'lifornia, have invented cer.

tain 'new and useful Improvements in Pumps, of which the following is a specification.

My invention relates particularly to deep well-centrifu al pumps.

It is one o ject'of my invention to pro vide a highly flexible dri/ving means for the pump runners that will not require the use offbear'ings or other supports throughout its'length.

Another object of this invention is to provide means of adjustment for a 'flexible shaft of the character indicated .where by its variation in length due to torsionl during operation may' 'be properly compensated for.

Another object is to provide a simple and positive connection betweenV the .flexible y shaft and the driving mechanism therefor.

i ure 5.

A further v'object 1s`to provide a means `operable by water pressure developed by the pump for indicating an abnormal tensional strain upon the flexible shaft.

It isa still further object to provide a suitable bearing forthe bottom of the shaft to carry the pump runners and shaft when not in operation' and during their initial stages whengoin into operation, together with means forv lu ricati'ng the same.

It is a still further object of my 'invention to provide anovel form of' bearing for the:

cable..

It is .a Afinal object of myV invention to provide -a pump `structure that is. simple,y in

isa section online vof Fig- Upper 1922. Serial'NlO. 565,828.

Figure 5 is an' enlarged'section of the cable holding mechanism, parts broken away.

Figure 6 1s a section throughthe coupling' of the cable to the pump bowl assembly shaft, parts broken away. y

Figure? is another embodiment of mounting a bearing upon the cable to workin a bearing formed integrally with the discharge easing, parts being broken away.

Figure 8 is a cross-section through the,

pump bowl and runner assembly showing lmy improved manner of indicating the pressure in the pump, parts being'broken away.

Referring more particularly to the draw.- ing, l show at; 1 the usual deep well casing constructionand at 2 is shownthe discharge column rising from the bearing bowl-3 up- Wardly to the discharge head 4;` Bolted to discharge head 4 is theV pulley bearing member v5 which has' an annular depression 6 formed in a false bottom member as 7, while `at 8 is shown a series of cap screwsvthreaded into the ,bottom r7 `and extending upwardly, into depression 6 so as to adjustthe'roller.

bearing portion 9. Thisadjustm'ent being made through the openings- 10 in the '.walls of bearing member 5 as shown. At 11 is shown a second annular depression ffirxnedy 'inthe `wall 12 of said bearing portion 5, a

`roller bearing 13 fitting therein as shown,

while at 14 and 15 is an opening in the bottom -7 and in the base portion through which a long annular 'member 16 passes as shown.

. They upper portionv of member 16 is threaded as Iat417 and has the bearingsupl port 18 slidably mounted thereon by means of key 19 `as shown, while set in the lower faces of support 18 is a bearing portion 20.

in alignment with bearing portion 9 as shown. The-upper portion of support 18 lhas a bearing portion 21 set therein in align'- ment with bearing portion 13 whileatv 22 is shown'a member threaded to screw over the bearing support member 18 andl supporting an adjustin nut A24las shown.

Above a justing nut driving .pulley 26 by means of the key 25 in member 16, whi e headed p portion setinto the'upper end of member 16, and having aseries of upstanding portions as 28, these being tapered and y threaded to receiveA a nut as at129. The

at 2 7 is a hexagonv 24 is Secured the l 32 which acts las a shaft' for -the bowl assem'f A'sa ^ connectingl cable 31- which is inner surface of these ta er threaded portions 28 havin inward y and upwardlypointing projections as shown.

Passing throughvthe center of portion 1'6 is a flexible Wire cable 31 which 'is held securely at its upper end by the tightening up of nut 29- Which causes the tapered portions 2 8v to draw inward thus' tightening up on cable 31 and .at the Sametime the` projections 30 are forced into the cable and their upwardly slanting points keep thev cable' from being pulled out froma downward strain as is readily' apparent. The cable v31fpasses down through the discharge-casing 2 and'i'nto a tubular member hly, the lower end of said-l cable having a solid portion 33 threaded Vthereon and having afconcavel surface as 34 in the end thereof. The lower bearing 35 of the suction` section is formed with a convex upper portion 36 of such proportions as to fit the concave lportion 34 as shown, which is screwed into a supporting member 37, while .at 38.v is a small orifice passing through member 35 ltoy aid in lubricating .the same when'the pump is started. In Figure 6 I show another embodiment o f means for connecting the cable 31 to the 30 regula-r solid bow-l assembly shaft as shown at, 35i-which has its `.lower end'concaved out as at 40 to fit the bearingportion 36 'as`\' shown in 'Figure 1. The shaft 39 is threadedjin'to a collar member 41 which is tapered' out at its upper end as at 42 to receive`l tapered members 43 having 'inwardlyanddownwardly projecting teeth as at 44 which grip the-cable 31'when` the cap member 45 is screwed down upon the same as shown. This construction effectually preventing the cable from being pulled out when under .the strain of 'actual operation;V f.

In Figure2 is shown another embodiment .ofsupprting the upper end of cable 31. `from that shown in Figure 1. He'reI show- "a solid member 46 passing upwardly through the :members- 14.-'.15-,18-22 and threaded to take nut 24 as shown at 47 insteadof ythe hollow member 16 shown in Figure 1.-

Th'e cable 31 being 4securely mounted in member46by means of the above described tapered portions 43 with-their now inwardly" and upwardly projecting prongs 44 and the i i' 6 cap45 as shown. -The keyway and'key 25 be- V 5 ing made to allow the solid portion46to `be raised or lowered as shown. 1

Asxdisclosedin the drawingthe shaft-v -member 16-46 is supported upon roller bearings 9-20 and the radial thrust is taken Vup bythe bearings 13--21 The pulley7 2G,

nut 24 Inembers 22-#18-3-16 all 4rotating to. gether and thusturning the impellers in' the bowl assemblyby means of the flexible wire perfectly free fxfrom bearings ofv any.- mnd om fthe dissolid shafts require.- means for overcoming the slight variations charge .head to thepump )bowl assembly as shown.

Asis-shown at 47 the .bowl'bearm portion is recessed out for a distance 'an thenr another recess 48' is made below the first 'o mentioned recessas shown. Ai'small'orifice 49 connecting recess portion-47 wlth themfterior of chamber 50 of said `bearing which is in turn connected to a pipe 51 bycored hole"52 passing to the said pipe as'shown. 75

'Ihe runner 53 of fsaid ybowl has anzup-y standing flange 54 whichis asliding fit in the vrecess47 of the bearing portionlas shown, the whole being so formed that at normalpump speed-the .upper edge of flange y 54is just below the`or-ifice49' as' shown in Figure 8-. `When this condition prevails -a water pressure is created in chamber 50 by means of the orifice 49 and thespace between the runner and the bearing which thus` causes the waterto forced up through.

the pipe 51 to the surface as shown at 55 where the-water runs` out of theopen end of the pipe. Duringy the operation ofthe pump, however, if the speed should'increase 90 l for any reason this inc'rease in speed would cause the flexible cable 31 ,to be drawn up j .'tighter' due to the increasedtorsional strain and this. would raise the runner 53 so that 1 lthe harige 47 wi1l raise up'v over thev orifice 951] 49 and cutoff the water supply to the pipe 51 thus causing the overlowfrom the'end 55 to cease. This `serves'asa-warningI to the \operator that the cable 31 xis too tight and hexloose'ns the screws 8 `in thepulley assem- 190;

bly '5 which allows'the beaingportion 9 to flower thus lowering ytheentire bearing assembly which again-bringsthe. impel'ler to the normahrunningposition astindicated by the starting of the water overflow from vthefpipe 51'as at 55. ff s By the use of a iiexible cable in a 'solid "shaft I can do away with l-bearf ings in the discharge casing column as well as the necessary lubrication system\ which Having, provided in -cable lengths dueto more or'less torsion when the' same is in operation and having Y v `also provided accurate means for Iindicat 116;

ing when this condition prevails aswell as means for SuP'PI'ting'the loweru'end of the I" few parts and economical" to manufacture,

install and operate.

In the embodiment, shown in 'Figure 7 va t member-56 'is shown made preferably of babbittandc'ast on cable 31 as an integral'.

bearing supported by The member 56 is so said cable At 57 is shown a discharge casing 2. proportioned with relation to bearing 57 that any movement of the cable through the bearing while the pump -is in operation will not reduce the amount of bearing surface of member 56 presented to the bearing 57.

It should be further pointed out that in its simplest form the invention contemplates a structure wherein the impeller may have sutlicient movement to obviate the necessity of providing adjusting devices orpressure indicators as above disclosed.
